6 Claims.

The present invention relates generally to surgical devices, and more particularly to an improved and novel wound clip.

There are in use today a number of wound clips, one of. the most popular types of which includes a pair of points struck out from the interior of the body of the clip. It is obvious that the die for effecting such struck out points must be of relatively considerable width in order to provide a struck out portion having the semblance of a point. Further, such points are often bent in the punching operation. Neither this type of wound clip nor any of the other clips on the market have points which are sufliicently sharp and small to function in the most highly desirable manner. A wound clip having blunt wide points causes undue pain in its initial clamping process and leaves noticeable scars when removed.

It is an object, therefore, of the present invention to provide a wound clip which has sharp, short, straight, thin points adapted to substantially painlessly enter the skin, to be easily withdrawn, and to leave substantially no scars.

Another object is to provide a wound clip formed from a blank having a point disposed at each end thereof.

Another object is to provide a device for supporting wound clips prior to use in a manner to prevent damage to the points thereof.

Another object is to provide a wound clip which is sturdy in construction, readily manufacturable, and adapted to efliciently and effectively close a wound.

Other objects and advantages will be apparent from the following description, taken in conjunction with the accompanying drawing, in which:

Fig. 2 is a plan view of the wound clip shown in Fig. 1;

Fig. 6 is a transverse section through a carrier showing a wound clip in position thereon;

Fig. 7 is a central longitudinal section through a modified wound clip;

Fig. 8 is a plan view of the blank from which the wound clip shown in Fig. 7 was formed;

Fig. 9 is a side view of another modified wound Fig. 10 is a plan view of the wound clip shown in Fig. 9;

' Fig. 11 is a plan View of the blank from which the wound clip shown in Fig. 9 was formed;

Fig. 12 is a side view of still another modified wound clip;

Fig. 13 is a plan view of the wound clip shown in Fig. 12;

Fig. 14 is a plan view of the blank-from which the wound clip shown in Fig. 12 was formed; and,

Fig. 15 is a section through a wound showing the relationship of the present wound clip to the skin.

Referring to the drawing more particularly bv reference numerals, there is shown in Figs. 1-3 a wound clip i 5 constructed as a preferred embodiment of the present invention, the blank it from which the wound clip 15 is formed being shown in Fig. 4.

The blank l6 includes an elongated rectangular main body I"! bounded by sides l8 and ends l9. Extending from each of the ends i9 is a sharp; short, narrow point 20. Slots or apertures 2! are struck out from the body I1. The points and the slots 2| are preferably disposed along the central longitudinal center line of the body H.

In the formation of the wound clip IS, the central portion of the body I1 is bowed to the configuration shown in Fig. 1. The end portions of the body I! are looped back so that the points 20 pass through the slots 2| and the ends l9 abut the upper surface of the body l'|.

A carrier 23 (Fig. 5) is provided for the wound clips IS. The carrier 23 is of trough cross-seqtion (Fig. 6), including a bottom 24 and sides 25 angularly disposed relative to the bottom 24. A holder tab 26 is formed integral with one end of the carrier 23.

The wound clips l5 slide onto the carrier 23 in the manner shown in Fig. 6, the points 20 contacting the outer surfaces of the sides 25. It is thus apparent that the points 20 are protected from damage.

In Fig. '7 is shown a modified wound clip 21, the blank 28 from which it is formed being shown in Fig. 8. The blank 28 includes an elongated rectangular body 29 defined by sides 30 and ends 3!. Sharp, narrow, short points 32 are formed integrally with the body 29 and extend outwardly from the ends 3|.

The wound clip 21 (Fig. '7) is formed by bowing the central portion of the body 29 and by looping the end portions of the body 29 in a manner to dispose the points 32 at substantially right angles and beneath the body 29.

In Figs. 9 and 10 there is shown another modified wound clip 34, the blank 35 of which is shown in Fig. 11. The blank 35 includes a main body 36 defined by sides 3'! and ends 38. Each of the sides 3'! is notched at 39 and 46. Each of the ends 38 has two sharp, short, narrow points 4| extending therefrom at the ends thereof. The points 4| in effect form continuations of the sides 31.

In the formation of the wound clip 34, the central portion of the body 33 is bowed. The end portions of the body 36 are looped back until the ends 38 contact the main body 36 and the points 4| extend through the notches 39 and 40 at substantially right angles to each other.

In Figs. 12 and 13 there is shown a still further modified wound clip 43, blank 44 of which is shown in Fig. 14. The blank 44 includes an elongated rectangular body 45 defined by sides 46 and ends 4?. Two spaced points 48 are struck from each side 46.

In the formation of the wound clip 43 the central portion of the body 45 is bowed, the end portions of the body 45 are looped back, and the points 48 are disposed at substantially right angles to the body 45 and to each other.

In Fig. 15 a wound clip is shown in relationship to the skin 55 and flesh 56 around a wound 57. The points 26 assume opposed positions through pinching together the halves of the body II, but do not touch. The main burden of holding the skin 55 pulled up as shown is carried by the end portions of the body ll, which compress the skin 55 and, therefore, the retaining points 20 need not be large.

The points 20 of the wound clip i5 and the points 32 of the wound clip 21 are particularly sharp, straight, short and narrow, inasmuch as they are formed by striking away the metal on one side and then on the other. A pin point sharpness is achieved due to the flow of metal during these operations. In other words, it is not contemplated that a V-shaped die be employed, although, of course, such could be em ployed with a degree of success. A narrow V-die is not particularly desirable, inasmuch as it would become enlarged and distorted with use. The points 4| of the wound clip 34 are similarly formed, although a wedge-shaped die could be employed. The points are short in order to prevent carrying of infection deep below the skin.

Short points are thus desirable and can be successfully used, for the looped portions of the body performs a compression task in holding the skin, and the points prevent slipping thereof.

The wound clips disclosed are preferably constructed of stainless steel, 2. metal much more desirable than German silver or alloys of which the present wound clips are constructed.

It is apparent that there has been provided a wound clip which fulfills all of the objects and advantages sought therefor. It is to be understood that the foregoing description and accompanying drawing have been given by way of illustration and example and not for purposes of limitation, the invention being limited only by the claims which follow.

What is claimed is:

l. A wound clip comprising a body having openings therein, and means for piercing the skin formed integral with the body, said means extending through the openings of the body.

2. A wound clip comprising a broad body, spaced openings in said body, and means for piercing the skin formed as integral extensions of the ends of the body, said extensions extending through said openings to the opposite side of the body and being disposed in opposed relationship.

3. A wound clip comprising a body of rectangular configuration, spaced openings in said body, and a point formed at each end of the body as an integral extension thereof, said points extending through said openings.

4. A wound clip comprising a body including a central curved portion and looped-back end portions, apertures in the curved portion, and points secured to the end portions and extending through the apertures.

5. A wound clip comprising a body, spaced apertures therein, a short, sharp, narrow point formed at each end of the body, the ends of the body being looped back upon itself so that the points extend through the apertures.

6. A wound clip comprising a broad body including a central portion and end portions, openings in the central portion, and a point formed as an extension of each end portion, said end portions being looped extending the points through the openings, the end edges of said end portions abutting the central portion at the openings.
